Choose the best term from the box to complete the sentence.
Question 1.
Numbers that are easy to compute mentally are called
Answer:
Compatible numbers
Explanation:
The numbers which are close to the actual numbers, and can be easily added, subtracted or divided orally are known as compatible numbers.”. These numbers are used for carrying out basic mathematical functions.
For example;
Compatible numbers for 232 and 11 are 240 and 12.
Question 2.
When a number cannot be divided evenly, the amount left over is called the _____________ .
Answer:
Remainder
Explanation:
Remainder is the value left after the division.
If a number (dividend) is not completely divisible by another number ( divisor) then we are left with a value once the division is done.
For example, 10 is not exactly divided by 3.
Since the closest value we can get is 3 x 3 = 9, which is 1 less than 10.
